RUNNER-IS AND PROPELLING MECHANISM FOR AUTOMOBILE-TRUCKS.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed January 27; 1917. Serial No. 144,954.

To all whom it may concern:

Be it known that I, ARTHUR BURROWS, a citizen of the United States, residing at Freedom, in the county of (lattaraugus and State of New York, have invented certain new and useful Improvements inRunners and Propelling Mechanism for Automobile- Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for attachment to automobilektrucks for converting the same for use as sleighs and comprises a simple and eiiicient device of this nature having various details of construction, combinations and arrangements of parts which will be l1ereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation showing the invention applied to the truck of an automobile, the wheels being removed.

Fig. 2 is a top plan view.

Fig. 3 is a sectional view Fig. l. I

Fig. L is a central vertical sectional view through one of the rear runners and driving mechanism, and

Fig. 5'is a sectional view Fig. 1.

Reference now being bad to the details of the drawings by numerals, 1 designates the frame of an automobile having a forward axle 2 and a rear axle 13 mounted within the casing -l. To the forward axle are connected the runners 5, taking the place on the skein of the axle occupied By the forward wheels of the automobile. To the forward end of each runner is connected a coiled spring 6 which inv turn is connected-to the frame 1.

To the rear axles are attached the run-- ncrs 7, one of which is shown in section in Fig. 4 of the drawings, and comprises a casing with an opening in the bottom and in the walls of which is journaled the shaft 14 upon which pivotal bars 10 are journaled, having slots 12. A plate l0 carries bolts 11 on line 3 -3 of on line 5-5 of passing through the slots 12 in the bars 10, and nuts 13 are mounted upon said bolts and adapted. to hold the bars 10 in different adjusted positions relatively to the plate 10; A shaft 8 is mounted in said plate 10 and" ing boxes 18, in which the driving axle 3 is mounted, and 20 is a sprocket wheel adapted to takethe place of the automobile wheel which has been removed from the axle. A stub shaft 14 carried by the bars 10 has keyed thereto a sprocket wheel 22,, about which, and the sprocket wheel 20, a chain 23 passes and forms means whereby the sprocket chain 16 may be driven. Asui table sleeve 3 fits over. the projecting end of the axle upon which the sprocket wheel 20 is mounted.

In order to regulate the tension of the spurs upon the ice or snow, springs 24 are fastened at their lower ends to the runners and their forward ends bear yieldingly against the rear ends of the bars 10. Screws 26 are pivotally connected at 27 to the run nor and pass through apertures in the springs, and nuts 28 are mounted upon the screws 26 and bear against the springs 24 and afford means for regulating the tension of said springs.

In operation, when the truck of an automobile is equipped with my propelling apparatus and runners, the same power may be applied to the driving of the endless chain, causing the spurs to bite into the snow or ice, the degree of pressure that the teeth may have upon the surface of snow or ice being regulated by the tension of the springs. The weight of the forward portion of the truck will come upon the front runners, while the weight of the rear portion will be thrown upon the runner portion at the lower end of the frame carrying the propelling mechanism.

What I claim to be new is 1. Runner and propelling apparatus for automobiles comprising runners adapted to be attached to the rear axle, each runner comprising a casing, shafts journaled in the screws fastened to the rear runners,

1 walls of the casing, a sprocket wheel fixed to the shaft, bars journaled upon the latter, a plate having adjustable connections with said bars, a shaft carried by said plate and a sprocket Wheel carriedby the shaft mounted upon the plate, sprocket chain connections between the sprocket wheels, spurs upon the sprocket chain movable through said slot, means connected to the rear axle for driving the shaft which is journaled in said casing, springs fastened to the latter and bearing against the ends of said bars, and nuts upon the screws adapted to bear against said SPIlD 'S.

2. Runners and propelling apparatus For automobiles, comprising rear runners, a driving shaft journaled near the forward end of each runner, a sprocket wheel rotating with said shaft, yielding bars pivotally mounted upon said shaft, recessed pi. ,ccured to said bars, andva stub shaft journaled in the walls of the recess, a sprocket Wheel journaled on said stub shaft, an endless otally mounted upon said shaft, a plate se-- cared to said bars and having a recessed end, a stub shaft journaled in the walls of the recessed end, a sprocket wheel journaled on the stub shaft, a spur sprocket chain passing about said sprocket wheels, springs secured to the runner, and adjustable means for holding the same yieldingly against said bars.

In testimony whereof I hereunto allix my signature in presence of two witnesses.
